    • A piston connected with a piston rod is fitted in a cylinder having a hydraulic fluid sealed therein. A damping force is generated through extension and compression disk valves and an orifice. Vehicle height adjustment is performed with a self-leveling mechanism by transferring the hydraulic fluid between the cylinder and a hydraulic fluid tank. A bladder of the hydraulic fluid tank is clamped between an outer flange portion of a partition member and a casing. Because the hydraulic fluid tank is formed without welding, it is possible to avoid contamination of the hydraulic fluid by welding sputter and thermal deformation. Provision of an O-ring on the outer flange portion can reduce the pressure acting from a reservoir on the clamped portion of the bladder and hence prevent dislodging of the bladder.
    • 与活塞杆连接的活塞安装在其中密封有液压流体的气缸中。 通过延伸和压缩盘阀和孔口产生阻尼力。 通过在液压缸和液压油箱之间传递液压流体,通过自动调平机构执行车辆高度调节。 液压油箱的气囊夹在分隔件的外凸缘部分和壳体之间。 由于液压油箱不经焊接而形成,因此可以通过溅射和热变形来避免液压油的污染。 在外部凸缘部分上设置O形环可以降低作用在气囊夹紧部分上的储存器的压力,从而防止气囊的移动。

    • A subject of the present invention is to provide an electric power steering capable of improving a contact ratio by using an hourglass worm to attain a higher output, and also performing a correction of a misalignment easily by simplifying remarkably a fitting operation of the hourglass worm. A worm gear system causes a hourglass worm 2 driven by an electric motor 4 to mesh with a worm wheel 3 provided to an output shaft 5, and a bearing 7 on the shaft end side, which bears rotatably the hourglass worm 2 is composed of a tapered roller bearing an outer ring of which can be separated. In a fitting operation, an inner ring 7a and rolling elements 7b are fitted into the hourglass worm 2 and also an outer ring 7c is fitted in advance in a gear housing 1. Then, the tapered roller bearing 7 is assembled in the gear housing 1 by moving the hourglass worm 2 obliquely to a rotating shaft line of the hourglass worm 2 in the gear housing 1 along a raceway of the outer ring 7c.
    • 本发明的目的是提供一种能够通过使用沙漏蜗杆来提高接触比以获得更高输出的电动助力转向器,并且通过简单地简化沙漏蜗杆的装配操作,容易地进行未对准的校正。 蜗轮系统使得由电动机4驱动的沙漏蜗杆2与设置在输出轴5上的蜗轮3啮合,并且轴端侧的可旋转地安装有沙漏蜗杆2的轴承7由 圆锥滚子轴承外圈可分离。 在装配操作中,将内圈7a和滚动元件7b装配到沙漏蜗杆2中,并且外圈7c预先安装在齿轮箱1中。 然后,通过沿着外圈7c的滚道将沙漏蜗杆2倾斜地旋转到齿轮箱1中的沙漏蜗杆2的旋转轴线,将锥形滚子轴承7组装在齿轮箱1中。
